* In the original games, Silver's Croconaw is underleveled in the second battle - it is at Lv. 16, though Totodile doesn't evolve into Croconaw until Lv. 18, a case different from Quilava/Feraligatr/Meganium below. This is fixed in the remakes, where his starter is at Lv. 18 for that battle.
* In HeartGold and SoulSilver, during the battle that takes place within the Goldenrod Tunnel, if Silver has Quilava, his entire team is two levels higher than if he had Meganium or Feraligatr. This is to compensate for the fact that Silver's Quilava isn't fully evolved during this battle, unlike his Meganium and Feraligatr. This starter-dependent level change does not occur in the original Gold and Silver.
